PHD Abstract
56 bulk milk samples were collected regularly every week for 7 months (January- July) from two organized dairy farms. In addition to 8 water samples, 8 equipment samples and 16 milkers samples were collected from each farm. In addition 25 bulk milk samples were randomly collected from 25 farmer farms.
Bacteriological examination of farm (1) milk samples revealed that the mean values of total bacterial, thermoduric, psychrotrophic, total coliform, faecal coliform, E.coli, S.aureus, Aeromonas and B.cereus counts were 3.63 x 10 5 + 1.28 x 105,1.6 x 104 + 8.5 x 103, 2.2 x 105 + 6.6 x 104, 4.5 x 104 +1.9 x 104, 3.2 x 103 + 1.1 x 103, 1.9 x 103 + 8.6 x 102, 2.5 x 103 + 9.2 x 102, 6.6 x 104 + 4.4 x 104 and zero /ml for cold season, while for warm season were 5.35 x 105 + 1.17 x 105, 9.01 x 103 + 2.8 x 103, 8.7 x 105 + 2.5 x 105, 7.2 x 104 +3.2 x 104, 2.3 x 103 + 1.7 x 103, 1.98 x 102 +8.5 x 101, 3.3 x 103 +1.9 x 103, 9.4 x 102 + 7 x 102 and 7.14 +7.14/ ml respectively.
